minal of the handlel3. of the pliers but it T 0 all whom'z't'mayc oacem. Be it knownthat LJOSEPH citizen of the United States'bf America, residing at Oceanside, intlie county of San Jo'sm ia: EQrisimmoii. oonAiisriiE, oi iirsonniii 4 F is iiRj a 1 Diego and State ofjCalifornia, have in- Ivented' new "and useful Improvements "in WVrench Attachments, of which the follows ing isa specificationv j The object in view is to' provide a simple inoreespecially adapted for work in connection with machine, shops, automobile ei1- gines and the like, and more especially to provide means'for increasing the range or scope of utility of tools of thepliers type giving an increased leverage with means of adjustment to suit the conditions under which the device is to be used; and with these objects in view the invention consists in the construction and combination of parts of which a preferred embodiiiient-. is shown in the drawing, wherein: .f.

Figure 1 is a View of a'device constructed in the form ofan attachment applied in the operative position to a tool ofthe. as pliers type, the same being shown'in iull? lines in its closed and in dotted lines in its open position. Figure 2 is'an edge view ofthe same. Figure 3 is a detail section on the plane'- indicated by the line 3 3 of Figure 2.' V Figure dis a detail view 01 oneend. of the operating lever to show the flat'sided pivot pin with which the same is provided; The device embodying the. invention is shown in the drawings as. applied to a tool of the gas pliers type as shown at- 10, said tool having the usual jaws 11 and handles 12' and-13, and the'att-ac'hment consists es-Q sentially. of anoperating leverl having terminal and intermediate means for engagem'ent respectively with the handles of the pliers; the terminal meansin the. construction illustrated consisting of a yoke 15 adapted for example, for. engagement with the handle 12, and the intermediate} means consisting of a bracket-16 for engage ment with or attachment to the handle'l As illustrated the bracket 16i's of a looped form designed at the closedeud oi theloop to form a seat 17 for the reception of the terwill be understood that other means of. attachinent of the bracket to the pliers handle may be adapted or ,the same may be formed as an extension or rigid part of said handle.

Ehe'means'of connection of the'terminal of theioperatinglever with the handle 12 of roughened grip portion201 1 I the pliers consist-sin the construction illustrated of a yoke o-flooped'form as shownin detail in Figure 3, the looped end of thef v same engaging thehandle 12 and being held against accidental displacement by trans verse retaining pin 21, ai'id theisides or arms of-the loop are provided with transversely registering seats 22; preferablyhaving. reduced inlet slots'23"in'communication with a longitudinal connectingslot 24, saidseat's" being adapted for engagement by the termi-, 113,1; pivot pin 25 carried by .the lever of which theextremityfitsjbetween the sides the seats and'int'o. the longitudinal communicating slot 2%, sothat the point oiconnec-- I tion of the operating lever with theyoke ,may bevaried to afiord any desiredfopening of the jaws of the pliers. Obviously the flattened pivot'pin 25 may be disengaged .56" from a seat and moved into the'communicatingslot only'whenthe parts are in the prescribed relative position. 'VVhen the tool is in use the pin is efficiently retained with I the seat with which it is engaged so as .to prov de against accidental displacement.

- Vitliithe construction described it will be obviousthat the attachment may be applied to gasor other pliers when required while permitting ofthe ordinary use of such pliers under other conditions, and that when so applied the attachment affords an increased leverage'whereby round or greasy objects 'fi'equently'in machine work may readily and efficiently be grasped and turned, and the futility of the device with the attachment will be particularly apparent in connection or roundedand perhaps jamniedor. rusted.

in place so "asfto resist the efforts to remove or loosen thelsame when applied through the 1 1 with boltsand nuts which have'become worn ordinary agencies. .The leverage of the. 013- ;j' V

crating member moreover may be varied to pliers.

Having described the invention, what I claim as new and useful is 1. An operating attachment for gas pliers having a lever and means for intermediately fulcruming the same to one of the handles of the pliers, and a looped yoke tor engaging the other handle of the pliers, said yoke being provided with a plurality of pivot pin seats having reduced neck portions in communication with a connecting slot, and said lever having a transversely flattened pivot pin forselective engagement with said seats.

2, An operating attachment for gas pliers having a lever, a bracket adapted for engagement with one handle of the pliers and having said lever fulcrumed at an intermediate point thereto, and a looped yoke for engagement with the other handle of said pliers and provided with a transverse retaining pin for securing the looped end of said yoke in engagement with the handle, said yoke being provided in its sides or arms with v a plurality of connected transversely registering seats, and the lever being terminally provided with a pivot pin for selective engagement with said seats. c 1
